Recent advances in technology have exposed enough computing power in easily available hardware that geometry synthesis algorithms that we were previously prohibitively compute-intensive are now a possibility. There is significant untapped potential in this area that so far has gone underutilized in existing simulations. Increasing the realism and accuracy of synthetic environments has become a priority, but current methods of simulating complex terrain features requiring manual, labor-intensive systems to generate certain complex terrain features accurately. In this effort, Cognitics will apply research from our Phase I effort to implement prototype software libraries and product(s) to simulate complex terrain features for urban traffic environments. This prototype software will be integrated into existing real-time simulation systems to make them capable of runtime modeling, integration, and interaction with complex terrain features. Cognitics has proven experience working with the storage, measurement, and analysis of geospatial data and software development, computational geometry and 3D visualization systems. Notably, the Principle Investigator for this SBIR, Kevin Bentley, is the software architect that designed the Master Database (MDB), currently used by SE Core.
